- Forefront technologies for the specimen preparation. In addition to traditional approaches, relying on well-grounded procedures such as laser and water jet cuts, among the others, cutting-edge manufacturing technologies operating at different scale levels (responsible for the definition of each hierarchical stage) are available.
Among them we can enumerate:
- 3D printing, allowing additive manufacturing of 3D hierarchical MMs starting from digital models;
- 3D Photolithography, based on a Nanoscribe system exploited to create hierarchical MMs with submicron resolution;
- Metal foams (based on inclusions of air or other gaseous pockets in the metal structure) and lattice structures manufacturing;
- Laser micromachining for polymer structuring (patterning, scribing, drilling, cutting, milling) at micron scale, using a dry, safe and low temperature direct photo-thermal ablation technique.
- Forefront and unique experimental facilities ideal for setting and exploring the most disparate experimental configurations and cutting-edge investigation tools covering a wide range of frequencies (from tens of Hz to MHz)
- A vast range of piezoelectric (contact, air-coupled and waterproof) transducers to excite and detect mechanical and acoustic waves in complex configurations
- Scanning Laser Doppler Vibrometer (SLDV) for the contactless acquisition
- The French biggest accessible water tank (8m x 6.5m x 6m) which makes the IEMN a unique experimental research environment in the Europe landscape for underwater applications
- Power amplifier and generator, dedicated frame for motorized displacements, etc
- About 1600 m2 of clean rooms (rooms where the particle concentration, temperature or humidity and pressure are controlled)
- Characterization centre for the measurement of the main electrical, microwave and electromechanical parameters of devices manufactured in clean room
- Impedance tube for acoustic characterization
- Anechoic, semi-anechoic and reverberating chamber for acoustic and vibroacoustic measurements, including laser vibrometry and sound intensity probe measurements
- Aura-lab (auralisation laboratory for psychoacoustic investigations of the effect of sound on human wellbeing)
- Full-scale sound transmission loss test facilities to measure the acoustic insulation performance of building materials and components, such as windows, dry-wall panels, doors.
- Cusing Concept M2 Metal 3D additive manufacturing facility for metal manufacturing with a build volume of 250x250x250mm, with the ability to prepare samples with common engineering materials, such as aluminum, titanium alloys or steel.
- High Resolution Optical Detection. Two laser vibrometers (Polytec, PDV-100 and PSV-400-H) can each measure the projected component of an object's surface vibration vector along the direction of the incident laser beam. The noncontact measurements can resolve the displacement amplitudes to as small as 0.1 pm, with a frequency range from near DC to MHz. An integrated CCD camera is used for monitoring of the measurement volume. With the aid of microscope objectives, measurements can be performed on micron-sized objects.
- 3-D Photolithography. Commercial 3D-Photolitography Nanoscribe system to create microstructures with submicron resolution. To fabricate microstructures a laser beam is guided through a microscope optic and focused within liquid or solid photoresist. Polymerization occurs at the focal point of the laser due to two-photon absorption.

- NEST: A full-scale modular research and innovation building where new technologies, materials and systems are tested, researched, honed and validated in realistic conditions. The close cooperation with partners from research, industry and the public sector helps launch innovative building and energy technologies on the market faster (www.empa.ch/web/nest).
The laboratory is equipped with the Polytec PSV-400 3D Scanning Laser Doppler Vibrometer.
This device consists of three individual Scanning Laser Vibrometers heads, data acquisition and controlling unit. The measurement is realized by pointing the three scanning heads from different angles to one spot simultaneously. Therefore, knowing the position of scanning heads and the geometry of the specimen it is possible to determine full velocity vectors. Due to its non-contact properties, very high resolution in both time and space domain, 3D SLDV is a perfect tool for measurements of the dynamics of metamaterials.
It will be an essential measuring device for experimental tests in the proposed project.
Supplementary equipment, which will be used during the project, are electromechanical shakers, signal waveform generators, amplifiers and various types of piezoelectric transducers.
Another device available at IFFM is a terahertz spectrometer (TPS Spectra 3000 from TerraView) for both transmission and reflection modes, supplied with a Large Sample Gantry Imaging system.
The system provides continuous coverage in the range 40 GHz- 10 THz.
Also, vibrothermography set–up consisting of ultrasound exciter, high-performance thermal imaging camera FLIR SC–5600 and FLIR software for data acquisition is available.
